Study Notes

Plant organs consist of three tissue systems: dermal, vascular, and ground tissue.

Also known as the epidermis, it is a single layer of tightly packed cells providing protection to young plant parts.
Root hairs enhance absorption of water and minerals from the soil.

Forms a continuous system throughout the plant, facilitating the transport of materials.
Xylem carries water and dissolved minerals upward from roots to shoots.
Phloem distributes food from leaves to roots and other non-photosynthetic parts of the plant.

Occupies the interior of the plant and contains three primary cell types: parenchyma, collenchyma, and sclerenchyma.

Roots serve as an anchor for the plant and absorb mineral nutrients from the soil.
Functionality of roots includes:
- Providing support to the plant structure.
- Absorbing, transporting, and storing nutrients.
- Utilizing root hairs to increase absorption efficiency.
